feat(docker): switch NFS mounts to HA cluster storage VIP
Updates mount-data.nix to mount all docker shares from
nfs.storage.home (Pacemaker vip-storage, 192.168.20.229) over docker's
eth1/vmbr2 interface instead of server.sweet.home over the LAN.
Adds haStorageNfsFqdn variable to variables.nix for the storage.home
zone FQDN so mounts survive a future VIP renumber without a rebuild.
Storage root changes from /tank (server ZFS pool) to /srv/ha-data
(HA cluster XFS-over-DRBD). Share subpaths are unchanged.
